• TRACE daemon (traced)
• Traffic daemon (trafd)
• VS daemon (vsd)
• Web linker daemon (weblinkerd)
• Web Tools daemon (webd)
• ZONE daemon (zoned)
KTRC Kernel RAS trace module.
L2SS L2SYS error messages indicate problems with the Layer 2 System manager that controls the Layer 2
forwarding engine and controls the learning/aging/forwarding functionality.
LACP LACP error messages indicate problems with the Link Aggregation Control Protocol module of the
Fabric OS.
LANCE LANCE error messages indicate problems with the LANCE module of the Fabric OS.
LFM LFM error messages indicate problems with the logical fabric manager module that is responsible
for making a logical switch use XISLs. This involves creating and managing LISLs in a logical fabric.
LOG RASLog subsystem.
LSDB The link state database is a part of the FSPF protocol that maintains records on the status of port
links. This database is used to route frames.
MCAST_SS The Multicast Sub-System messages indicate any problems associated with the Layer 2 and Layer 3
Multicast platform support, including allocation of global platform resources such as MGIDs,
hardware acceleration resources for Multicast, and route programming into the hardware (Layer 2
EXM for IGMP Snooping).
MAPS The MAPS module identifies and reports anomalies associated with the various error counters,
thresholds, and resources monitored on the switch.
MFIC MS-FICON messages relate to Fibre Connection (FICON) installations. Fibre Connection control unit
port (FICON-CUP) messages are displayed under the FICU module.
MM MM message indicate problems with the management modules.
MPTH Multicast path uses the shortest path first (SPF) algorithm to dynamically compute a broadcast tree.
MQ Message queues are used for interprocess communication. Message queues allow many messages,
each of variable length, to be queued. Any process or interrupt service routine (ISR) can write
messages to a message queue. Any process can read messages from a message queue.
MS The Management Service enables the user to obtain information about the Fibre Channel fabric
topology and attributes by providing a single management access point. MS provides for both
monitoring and control of the following areas:
• Fabric Configuration Server: Provides for the configuration management of the fabric.
• Unzoned Name Server: Provides access to Name Server information that is not subject to zone
constraints.
• Fabric Zone Server: Provides access to and control of zone information.
MSTP MSTP error messages indicate problems with Multiple Spanning Tree Protocol modules of the Fabric
OS.
